This is the concept of exponential growth, To get the number of bacteria after 10 days we use the formula:
f(t)=ae^(kt)
where;
a=initial number=5000
k=constant of proportionality= 0.04
t=time=10 days
f(t)=future number
thus the number of bacteria in 10 days will be:
f(t)=5000e^(0.04*10)
f(t)=7,459.12
The answer is 7,459.12
C=dπ and r+r=d so 3+3=6 and 6π≈18.84 so the circumference would be 18.84
1 lap to ten minutes or 1:10 due to the fact that it takes ten minutes to run one lap. hope this helps, have a nice day :)
